I don't know

Gene rated Amber : From feedback from Genomics England Clinical team (Anna de Burca and Meriel McEntagart): Extension of panel scope - minor feature / Broader phenotype: Pelizaeus-Merbacher/Spastic paraplegia 2 - is neuropathy a feature?

Panel Version: 0.86
This gene has changed ratings because the panel for R78 was going to be a broad panel (to include conditions where neuropathy is part of a more complex phenotype or where there is overlap with another neurological presentation eg. HSP) but subsequently during the follow up call on 21st June with the Test Group it was agreed that it was more clinically relevant for R78 to be restricted to genes that are associated with isolated neuropathy, which this panel represents. For genes that represent the broader phenotype see https://panelapp.genomicsengland.co.uk/panels/85/.

Null mutations cause a neuropathy
Created: 16 May 2019, 8:41 p.m.
Loss of function mutations cause demyelinating neuropathy with spasticity
Created: 9 Dec 2015, 8:50 a.m.

Mode of inheritance
X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)
